[PMID: 34953598 DOI: 10.1016/j.ejogrb.2021.08.034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2020] [Revised: 06/18/2021] [Accepted: 08/26/2021] [Indexed: 01/09/2023]
Abstract
OBJECTIVE To investigate the influence of the Single Nucleotide Polymorphisms (SNPs) TP53 rs1625895, TP73 rs3765730, MMP9 rs17576, and MTHFR rs868014 on ovarian reserve (OR) in infertile patients. STUDY DESIGN A prospective cross-sectional study was carried out in 145 infertile women. The patients were divided into two groups according to ovarian reserve, characterized by association between AMH levels and AFC:After patient distribution, both groups were compared (LOR X NOR) regarding the genotypes of the SNPs TP53 T/C rs1625895, TP73 G/A rs3765730, MMP9 Gln/Arg rs17576, and MTHFR A/G rs868014. RESULT(S) The frequency of the TP53-T/T genotype was greater in the LOR and the TP53-C/C genotype was more frequent in patients with NOR. This association was confirmed by the frequency of alleles, where the presence of the T allele was significantly higher in patients who exhibited LOR (P = 0.0003). The frequency of the TP73-G/G genotype and of the G allele was higher in the LOR group (P = 0.01). Considering the MMP9 gene, the frequency of the Gln/Gln genotype was higher in the LOR group. However, the Gln/Arg genotype and the Arg allele prevailed in the NOR group (P = 0.006). The frequency of the MTHFR-A/A genotype was higher in the LOR group, whereas that of the MTHFR-GG genotype was higher in the NOR group. The presence of allele A was significantly higher in the LOR group (P = 0.002). The regression analysis shows that patients who present the TP53-T/T, TP73-G/G, MMP9-Gln/Gln, and MTHFR-A/A genotypes are 3.6X, 3.1X, 3.2X, and 3.7X more likely of having LOR, respectively. In addition, the association of the TP53/TT + TP73/GG genotypes increased the chance of women being included in the LOR group in 5.7-fold. CONCLUSION(S) The genotypes TP53-T/T, TP73-G/G, MMP9-Gln/Gln, and MTHFR-A/A increase the chance of women to exhibit LOR. These polymorphisms could be useful as genetic markers of low ovarian reserve in infertile patients.

Abstract
The tortuous nature of the ovine cervix restricts the transcervical passage of the cannula, and many studies have aimed to understand the endocrine mechanism of the remodelling of cervical tissue in adult ewe. However, little is known about the remodelling of the cervical tissue during the prepubertal development of the lambs. To obtain histochemical and biochemical evidence about the nature of the prepubertal development of the cervix of the ewe, cervices of Corriedale lambs obtained at 0, 1, 2, 4, 6 and 8 months of age (n = 5 to 6 in each) were processed. Neutral and acidic glycosaminoglycans (by PAS-Alcian stain) were weakly in the cervical stroma and not shown change during the development, whereas the percentage volume of fibrillar collagen (by van Gieson stain) increases throughout the experimental period in the superficial fold stroma and deep wall stroma (p < 0.05). The relative cervical weight (g/kg of body weight) and the collagen concentration (by spectrophotometry, mg/mg wet tissue) showed an early decreasing phase from months 0 to 4 and a later increasing phase from months 4 to 8 (p < 0.05). The latent form of matrix metalloproteinase-2 (MMP-2) detected by gelatin zymography (ng/mg protein) decreased from months 0 to 2 and increased from months 4 to 8, whereas the activated form decreased from months 0 to 2, remained low until month 6 and then recovered on month 8 (p < 0.0001). Data suggest that the relative cervical weight biphasic pattern during the development is related to MMP-2-dependent changes in the collagen content.

Spatio-temporal expression profile of matrix metalloproteinase (Mmp) modulators Reck and Sparc during the rat ovarian dynamics. Reprod Biol Endocrinol 2018; 16:116.

Abstract
BACKGROUND Matrix metalloproteinases (Mmps) and their tissue inhibitors (Timps) are widely recognized as crucial factors for extracellular matrix remodeling in the ovary and are involved in follicular growth, ovulation, luteinization, and luteolysis during the estrous cycle. Recently, several genes have been associated to the modulation of Mmps activity, including Basigin (Bsg), which induces the expression of Mmps in rat ovaries; Sparc, a TGF-β modulator that is related to increased expression of Mmps in cancer; and Reck, which is associated with Mmps inhibition. However, the expression pattern of Mmp modulators in ovary dynamics is still largely uncharacterized. METHODS To characterize the expression pattern of Mmps network members in ovary dynamics, we analyzed the spatio-temporal expression pattern of Reck and Sparc, as well as of Mmp2, Mmp9 and Mmp14 proteins, by immunohistochemistry (IHC), in pre-pubertal rat ovaries obtained from an artificial cycle induced by eCG/hCG, in the different phases of the hormone-induced estrous cycle. We also determined the gene expression profiles of Mmps (2, 9, 13 14), Timps (1, 2, 3), Sparc, Bsg, and Reck to complement this panel. RESULTS IHC analysis revealed that Mmp protein expression peaks at the early stages of folliculogenesis and ovulation, decreases during ovulation-luteogenesis transition and luteogenesis, increasing again during corpus luteum maintenance and luteolysis. The protein expression patterns of these metalloproteinases and Sparc were inverse relative to the pattern displayed by Reck. We observed that the gene expression peaks of Mmps inhibitors Reck and Timp2 were closely paraleled by Mmp2 and Mmp9 suppression. The opposite was also true: increased Mmp2 and Mmp9 expression was concomitant to reduced Reck and Timp2 levels. CONCLUSION Therefore, our results generate a spatio-temporal expression profile panel of Mmps and their regulators, suggesting that Reck and Sparc seem to play a role during ovarian dynamics: Reck as a possible inhibitor and Sparc as an inducer of Mmps.

Abstract
Tissue reorganization during ovulation and corpus luteum formation involves a coordinated action of matrix metalloproteinases (MMPs) and tissue MMP inhibitors (TIMPs). In this study we investigated the cellular source of ovarian MMPs and TIMPs. Cells isolated from the preovulatory human follicle were cultured after immunobead depletion of CD45-expressing cells, which allowed differential assessment of leukocyte and granulosa-lutein cell fractions. Secretion of MMP-9 by follicular fluid-derived cells was associated with the presence of leukocytes. Granulosa-lutein cells synthesized low levels of MMP-9 but failed to secrete this enzyme that presumably accumulated in the cytoplasm, indicated by an increased MMP-9 expression of luteinized cells in sectioned midluteal phase corpora lutea. Synthesis and secretion of TIMP by follicular fluid-derived cells was associated with granulosa-lutein cells. TIMPs derived by granulosa-lutein cells failed to inhibit MMP-related pericellular proteolysis. The findings support a two-cell model of periovulatory MMP/TIMP release, in which leukocytes secrete MMPs and granulosa-lutein cells release TIMP, suggesting that there exists an intriguing interaction among cells that intertwingle during ovulation and corpus luteum formation.

Abstract
PURPOSE To evaluate the latent and active forms of MMP-2 and MMP-9 in human semen samples and to investigate their association with semen parameters. METHODS Basic semen analysis was performed in 82 semen samples. Seminal plasma was analyzed with gelatin zymography. RESULTS Both latent and active forms of MMP-2 and MMP-9 were detected in human seminal plasma. The latent forms were the predominant ones. MMP-2 and MMP-9, either in latent or active forms, were not correlated with semen parameters. ProMMP-9 levels were higher in semen samples with abnormally low concentration (< or = 19 x 10(6)/ml) compared with semen samples with concentration > or = 50 x 10(6)/ml. CONCLUSION MMP-2 and MMP-9 are both present in human semen. The latent forms of both MMPs are the predominant ones. ProMMP-9 is elevated in samples of low sperm concentration.

Abstract
The corpus luteum (CL) is a transient endocrine organ that secretes progesterone to support early pregnancy. If implantation is unsuccessful, luteolysis is initiated. Extensive tissue remodeling occurs during CL formation and luteolysis. In this study, we have studied the possible involvement of MMP-2, -9, -14, and their inhibitors, TIMP-1, -2, -3 in the CL of cycling rhesus monkey at various stages by in situ hybridization, immunohistochemistry and microscopic assessment. The results showed that the MMP-2 mRNA and protein were mainly expressed in the endothelial cells at the early and middle stages of the CL development, while their expressions were observed in the luteal cells at the late stage during luteal regression. MMP-9 protein was detected in the CL at the early and middle stages, and obviously increased at the late stage. The expressions of MMP-14 and TIMP-1 mRNA were high at the early and late stages, and low at the middle stage. TIMP-2 mRNA was high throughout all the stages, the highest level could be observed at the late stage. The TIMP-3 production was detected throughout all the stages, but obviously declined during CL regression. MMP-9, -14 and TIMP-1, -2, -3 were mainly localized in the cytoplasm of the steroidogenic cells. The results suggest that the MMP/TIMP system is involved in regulation of CL development in the primate, and the coordinated expression of MMP-2, -14 and TIMP-1, -3 may have a potential role in the CL formation and the functional maintaining, while the interaction of MMP-2, -9, -14 and TIMP-1, -2, -3 might also play a role in CL regression at the late stage of CL development in the primate.

Abstract
As prerequisite for development and maintenance of many diseases angiogenesis is of particular interest in medicine. Pathologic angiogenesis takes place in chronic arthritis, collagen diseases, arteriosclerosis, retinopathy associated with diabetes, and particularly in cancers. However, angiogenesis as a physiological process regularly occurs in the ovary. After ovulation the corpus luteum is formed by rapid vascularization of initially avascular granulosa lutein cell tissue. This process is regulated by gonadotropic hormones. In order to gain further insights in the regulatory mechanisms of angiogenesis in the ovary, we investigated these mechanisms in cell culture of human granulosa lutein cells. In particular, we determined the expression and production of several angiogenic factors including tissue inhibitor of matrix metalloproteinases-1 (TIMP-1), Leptin, connective tissue growth factor (CTGF), meningioma-associated complimentary DNA (Mac25), basic fibroblast growth factor (bFGF), and Midkine. In addition, we showed that human chorionic gonadotropin (hCG) has distinct effects on their expression and production. hCG enhances the expression and production of TIMP-1, whereas it downregulates the expression of CTGF and Mac25. Furthermore it decreases the expression of Leptin. Our results provide evidence that hCG determines growth and development of the corpus luteum by mediating angiogenic pathways in human granulosa lutein cells. Hence we describe a further approach to understand the regulation of angiogenesis in the ovary.

Abstract
CONTEXT The molecular mechanisms of luteolysis and its inhibition during maternal recognition of pregnancy remain unclear. OBJECTIVE The objective of this study was to investigate the differential regulation of connective tissue growth factor (CTGF) expression in human corpora lutea using in vivo and in vitro models. DESIGN Corpora lutea from different stages of the luteal phase and after luteal rescue with human chorionic gonadotropin (hCG) were studied. Primary cultures and cocultures of luteinized granulosa cells and luteal fibroblast-like cells were performed. SETTING This study was performed at the research center of a university teaching hospital. PATIENTS Women with regular cycles having hysterectomy for nonmalignant conditions and women undergoing oocyte collection for assisted conception were studied. INTERVENTIONS CTGF localization was determined by in situ hybridization, and expression by quantitative RT-PCR. OUTCOMES The outcome measures were the effect of hCG on the expression and localization of CTGF mRNA in human corpora lutea and the effect of hCG on CTGF expression in primary cultures of luteinized granulosa cells and luteal fibroblast-like cells. RESULTS Luteal rescue reduced CTGF expression compared with that in the late luteal phase (P < 0.05). CTGF expression was localized to fibroblast-like cells and endothelial cells of larger blood vessels, not to steroidogenic cells. The expression of CTGF by fibroblast-like cells in vitro was not regulated by hCG. When cocultured with luteinized granulosa cells, fibroblast-like cell CTGF expression was inhibited by hCG (P < 0.001). This effect was independent of stimulated progesterone concentrations and was not blocked by follistatin or indomethacin. Both IL-1alpha (P < 0.05) and cAMP (P < 0.001) inhibited CTGF expression in fibroblast-like cells. CONCLUSIONS These results provide evidence for negative regulation of CTGF by hCG during luteal rescue mediated by paracrine signals.

Abstract
OBJECTIVE To investigate the role of matrix metalloproteinase-9 (MMP-9) in the pre-ovulatory follicular fluid and culture media during in vitro fertilisation (IVF) cycle and to develop the zymographic pre-diagnosis marker for successful implantation and pregnancy in human IVF. DESIGN Controlled clinical study. SETTING IVF Laboratory, Women's Hospital Infertility Clinic and Dongguk University, Korea. SAMPLE Women undergoing in vitro fertilisation treatment. METHODS Experiments were designed for controlled clinical study with women undergoing IVF treatment. MMP-9 expressions in follicular fluid and culture media samples that had been collected during transvaginal oocyte retrieval were measured using zymography. MMP-9 activities and expressions were strongly correlated to a higher rate of fertilisation and pregnancy. MAIN OUTCOME MEASURES Fertilisation rates and ultrasonic evidence of intrauterine pregnancy by four weeks after embryo transfer. RESULT MMP-9 activity was significantly higher in the pregnant group than in the non-pregnant group (P < 0.01). In contrast, MMP-2 activity was present in the follicular fluid and culture media of all women, and no difference in its expressions was found between the pregnant and non-pregnant groups. No correlation was found between the MMP-9 expression in follicular fluid and culture media and the fertilisation rates. CONCLUSION The expression of MMP-9 in the follicular fluid and culture media is a prerequisite for successful pregnancy in IVF cycle. The zymography of MMP-9 activity in follicular fluids of human and culture media was developed as a pre-diagnostic method and zymographic diagnosis marker for successful fertilisation, implantation and pregnancy in human IVF.

Abstract
The human corpus luteum expresses genomic progesterone receptors (PRs) suggesting that progesterone may have an autocrine or paracrine role in luteal function. We hypothesised that the reduction in luteal PR reported in the late-luteal phase augmented progesterone withdrawal and had a role in luteolysis. We therefore tested the hypothesis that luteal rescue with human chorionic gonadotrophin (hCG) would maintain PR expression. PR was immunolocalised to different cell types in human corpora lutea (n = 35) from different stages of the luteal phase and after luteal rescue with exogenous hCG. There was no change in the staining intensity of theca-lutein cell or stromal cell PR throughout the luteal phase or after luteal rescue. In the late-luteal phase, granulosa-lutein cell PR immunostaining was reduced (P < 0.05) but the trend to reduction was also seen after luteal rescue with hCG (P = 0.055). To further investigate the effect of hCG on granulosa-lutein cell PR expression, an in vitro model system of cultured human luteinised granulosa cells was studied. Cells were cultured for 12–13 days exposed to different patterns of hCG and aminoglutethamide to manipulate progesterone secretion (P < 0.0001). Expression of PR A/B and PR B isoforms was examined by quantitative real-time RT-PCR. PR A/B mRNA was lower (P < 0.05) after 11–13 days of culture than after 7 days of culture. This reduction could not be prevented by hCG in the presence (P < 0.05) or absence (P < 0.05) of stimulated progesterone secretion. The expression of PR B mRNA showed a similar pattern (P = 0.054). Simulated early pregnancy in vivo and hCG treatment of luteinised granulosa cells in vitro did not appear to prevent the down-regulation of PR seen during luteolysis.

Abstract
Angiogenesis is essential for normal growth and function of the corpus luteum. The roles of various angiogenic factors in these events are being elucidated. Endocrine gland vascular endothelial growth factor (EG-VEGF) has recently been described in the human ovary. To define the localization of EG-VEGF mRNA in the corpus luteum and determine changes in its expression, dated human corpora lutea were studied at the early, mid-, and late luteal phases. Quantitative RT-PCR was employed to determine changes in EG-VEGF mRNA and compare expression to its related factor prokineticin-2 and the established angiogenic factor, VEGF. In situ hybridization was used to localize sites of production of EG-VEGF. To investigate whether expression of EG-VEGF was under the influence of LH or progesterone, luteinized granulosa cells were stimulated with human chorionic gonadotropin in the presence or absence of a progesterone synthesis inhibitor. EG-VEGF mRNA increased throughout the luteal phase, whereas there was no change in VEGF mRNA. The relative abundance of RNAs based upon PCR signal intensity showed that VEGF and EG-VEGF were highly expressed, whereas expression of prokineticin-2 was low. EG-VEGF mRNA was localized predominantly to granulosa-derived cells of the corpus luteum. Human chorionic gonadotropin stimulated both VEGF and EG-VEGF mRNA in vitro, but the level of expression was not influenced by progesterone. These results establish that in the human corpus luteum EG-VEGF is principally derived from granulosa lutein cells and that its synthesis is highest during the mid- to late luteal phase.

Abstract
The matrix metalloproteinases (MMPs) are part of an expanded family of proteins called the astacin family of zinc metalloproteinases. The MMPs, probably balanced by their tissue inhibitors of metalloproteinases (TIMPs), are essential effectors of developmental processes participating in cell migration, cell proliferation, apoptosis and tissue morphogenesis. The MMPs regulate the function of biologically active molecules as well as fulfilling an important role in endothelial cell invasion, angiogenesis and in tumor progression. The dynamic normal physiology of the human reproductive system involves almost all of the above-mentioned aspects of MMPs activity. This review presents and discusses new insights into the role of MMPs, and their TIMPs, in human endometrial cycle and ovarian function.

Abstract
The matrix metalloproteinases (MMPs) and their endogenous inhibitors, tissue inhibitors of metalloproteinases (TIMPs), may mediate the dramatic structural and functional changes in the corpus luteum (CL) over the course of its life span. In addition to regulating MMP activity, TIMPs are also involved in a variety of cellular processes, including cell proliferation and steroidogenesis. In a series of initial studies, we determined that matrix metalloproteinase inhibitory activity was present in protein extracts from early (4 days old, estrus = day 0), mid (10-12 days old) and late (16 days old) CL (n = 3 for each stage). Reverse zymography revealed four metalloproteinase inhibitory protein bands with relative molecular masses that are consistent with those reported for TIMP-1 to -4. In order to gain a better understanding of TIMPs and their role in luteal function, we further characterized this inhibitory activity with a particular focus on the temporal and spatial expression of TIMP-1 and TIMP-2 in the bovine CL. Northern blotting revealed that the TIMP-1 transcript (0.9 kb) was expressed at a higher (p < 0.05) level in early and mid cycle CL than in the late stage. In contrast, two TIMP-2 mRNA species, one major 1 kb species and one minor 3.5 kb species, were significantly (p < 0.05) increased in the mid and late cycle CL than in the early. Western blotting analyses demonstrated no differences in TIMP-1 (29 kDa) protein levels between early and mid stages, while its levels decreased (p < 0.05) from the mid to late stage CL. Conversely, TIMP-2 (22 kDa) protein was detected at a low level in the early CL, but significantly (p < 0.05) increased in the mid and late stages. Immunohistochemistry revealed that both TIMP-1 and -2 were localized to large luteal cells from all three ages of CL. TIMP-1 was also localized in capillary smooth muscle cells, while TIMP-2 was restricted to the endothelial cells in the capillary compartment. In conclusion, the different temporal expression patterns of TIMP-1 and TIMP-2 suggest that TIMP-1 may be important for luteal formation and development, while TIMP-2 may play significant roles during luteal development and maintenance. Furthermore, the distinct localization of these two inhibitors in the vascular compartment indicates that they may serve diverse physiological functions during different stages of luteal angiogenesis.

Abstract
The ovary and uterus undergo extensive tissue remodeling throughout each reproductive cycle. This remodeling of the extracellular environment is dependent upon the cyclic hormonal changes associated with each estrous or menstrual cycle. In the ovary, tissue remodeling is requisite for growth and expansion of the follicle, breakdown of the follicular wall during the ovulatory process, transformation of the postovulatory follicle into the corpus luteum, as well as the structural dissolution of the corpus luteum during luteal regression. In the uterus, there is extraordinary turnover of the endometrial connective tissue matrix during each menstrual cycle. This turnover encompasses the complete breakdown and loss of this layer, followed by its subsequent regrowth. With implantation, extensive remodeling of the uterus occurs to support placentation. These dynamic changes in the ovarian and uterine extracellular architecture are regulated, in part, by the matrix metalloproteinase (MMP) system. The MMP system acts to control connective tissue remodeling processes throughout the body and is comprised of both a proteolytic component, the MMPs, and a regulatory component, the associated tissue inhibitors of metalloproteinases. The current review will highlight the key features of the MMPs and tissue inhibitors of metalloproteinases, focus on the changes and regulation of the MMP system that take place throughout the estrous and menstrual cycles, and address the impact of the dynamic tissue remodeling processes on ovarian and uterine physiology.

Abstract
OBJECTIVE To investigate the regulation of MMP-9, TIMP-1, and progesterone via three signal transduction pathways in luteinized granulosa cells from normal ovulatory and PCOD women. DESIGN In vitro study. SETTING Laboratory for Research in Reproductive Sciences, Department of Obstetrics and Gynecology, Ha'Emek Hospital, Afula, Israel. PATIENT(S) Ten normal ovulatory and 10 women with polycystic ovary disease (PCOD) treated in an assisted reproduction program. INTERVENTION(S) Cultured cells were exposed to phorbol 12-myristate 13-acetate (TPA), acting via protein kinase C (PKC), to epidermal growth factor (EGF), acting via protein tyrosine kinase (PTK), and to forskolin, acting via protein kinase A (PKA). MAIN OUTCOME MEASURE(S) Secretion of MMP-9, TIMP-1, and progesterone. RESULT(S) Phorbol 12-myristate 13-acetate elicited an increase in MMP-9 and TIMP-1 secretion in both groups and apparently did not affect progesterone secretion. Epidermal growth factor did not change significantly neither MMP-9 nor TIMP-1 secretion but dose dependently decreased MMP-9-TIMP-1 ratio and increased progesterone secretion in the PCOD group. Forskolin inhibited MMP-9 activity and increased TIMP-1 and progesterone secretion in both groups. Progesterone production was inversely related to the ratio of MMP-9-TIMP-1 regardless of cell origin. CONCLUSION(S) In this preliminary study, similar and divergent patterns have emerged in the regulation of MMP-9 and TIMP-1 in human luteinized granulosa cells. Repressing MMP-9-TIMP-1 ratio may have an important modulatory effect on progesterone secretion.
